The vibe: More is more at the three-tiered stage set that is Encore Beach Club. Serious glam is the order of the day, especially in one of the eight private bungalows with views of the Strip, private dipping pools, and more. Suit up: Dress to impress. You’ll see plenty of bling by this pool. And things heat up on Thursday and Friday nights for the pool’s Encore Beach Club at Night—now in its second year. Think complicated, lingerie-inspired suits from La Perla and Hervé Léger. Encore doesn’t play around about its dress code, which you can find on its site. Don’t miss: Sets by Diplo, Alesso, Kaskade. Flosstradamus, and Skrillex, among others. 702-770-7300

The vibe: The Côte d’Azur-themed, private Azure pool has always felt like an exclusive enclave, past the bachelor parties of the main complex into a world where 11 air conditioned cabanas come with all the modcons, plus Canyon Ranch SpaClub massages on offer, and menu items from Wolfgang Puck. Suit up: Think “country club meets day club,” the motto of the pool as it has revamped to feel even more VIP this year. White on white is a no-brainer. Don’t miss: New summer cocktails for 2016, like Rosé all Day: Jean-Luc Colombo Cape Bleue rosé, Cointreau, summer berry shrub, and Prosecco. 702-767- 3724

The vibe: Grown-up luxe. Mandarin’s sophisticated pool deck on the eighth floor of the hotel is pure urban chic—and refreshingly non-meat-markety. You’ll run into the same crowd you mingled with in Cannes or saw in St. Bart’s at Thanksgiving in this sedate little group of 17 cabanas. Suit up: Subdued luxury and a floaty caftan dovetail with this pool scene’s message: “I’m fabulous, but not trying too hard.” Don’t miss: Raw vegan smoothies and bikini-friendly fare like Hokkaido Scallop Ceviche at The Pool Café. 888-527-8342

The vibe: Red Rock’s three-acre Pool Backyard, which also serves as an entertainment venue for up to 3,000 people, attracts plenty of wellheeled locals, as well as weekenders in to use the resort as a base for exploring Red Rock Conservation Area. Suit up: There’s a distinctly boho vibe here, so flip flops and casual wear are the order of the day, though our suburban moms look different than in other cities—so expect plenty of elevated suits, too. Don’t miss: Poolside blackjack at the Sandbar, and “Silent Savasana,”—evening poolside yoga. 11011 W. Charleston Blvd.; 702-797-7517
